[All JN0-664 Questions]

Exhibit

R2 is receiving the same route from R1 and R3. You must ensure that you can load balance traffic for that route.

Referring to the exhibit, which configuration change will allow load balancing?

AConfigure the multipath parameter under the global BGP configuration.

BApply the prepend policy as an import policy under group R1.

CConfigure the multipath multiple-as parameter under the global BGP configuration.

DApply the prepend policy as an import policy under group R3.

Show Suggested Answer

Suggested Answer: B, D, E

Junos platforms use different mechanisms to evaluate incoming traffic for CoS purposes, such as:

Behavior aggregate classifiers: These classifiers use a single field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined or user-defined values.

Fixed classifiers: These classifiers use a fixed field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined values.

Multifield classifiers: These classifiers use multiple fields in a packet header to classify traffic into different forwarding classes and loss priorities based on user-defined values and filters.

Rewrite rules and traffic shapers are not used to evaluate incoming traffic for CoS purposes, but rather to modify or shape outgoing traffic based on CoS policies.

I agree with C, but I’m curious about the impact on routing!

Wait, can you really load balance with just prepending? Sounds off.

Definitely going with C, it’s the standard for multiple AS!

I feel like I should go with option C since it mentions multiple-as, but I can't shake the feeling that I might be overthinking it.

I’m a bit confused about the differences between the multipath and multiple-as options. I think I might have seen a question that emphasized using multiple-as for load balancing.

This question feels familiar! I think I practiced a similar one where we had to balance routes from multiple peers. I wonder if the prepend policy could actually help here.

I remember studying BGP multipath configurations, but I'm not sure if it's just the multipath parameter or if I need to consider multiple-as as well.

Prepending the route under the import policy won't work here. That would just make one of the paths less preferred, not enable load balancing.

Okay, I think I've got it. The key is to configure the multipath parameter under the global BGP configuration to enable load balancing for that route.

Hmm, I'm a bit confused by the wording here. I'll need to re-read the question and exhibit a few times to make sure I understand what they're asking.

This looks like a tricky BGP configuration question. I'll need to think through the options carefully.

Hmm, C seems like the clear winner here. Configuring multipath multiple-as is the only way to actually load balance the traffic across the two BGP sessions. Unless R1 and R3 are trying to pull a fast one on us, that is.

I'm feeling confident about C. The other options just don't seem to address the requirement for load balancing the route. Although, I do wonder if R1 and R3 are secretly rooting for me to pick the wrong answer...

Let's go with C then. It's our best shot at achieving load balancing for that route.

Haha, I bet the answer is C because the question said 'load balance' and that's the only option that mentions multipath. Maybe R1 and R3 are trying to send me on a wild goose chase with those other answers!

I was leaning towards B, but C makes more sense since the question specifically mentions load balancing. Prepending the route would just make it less preferred, not actually load balance it.

I think the correct answer is C. Configuring the multipath multiple-as parameter under the global BGP configuration would allow load balancing for the route received from R1 and R3.
